Abstract

Low-pressure gas discharge lamp provided with a discharge vessel (1) enclosing a discharge space provided with a gas filling in a gastight manner, said discharge vessel (1) having tubular end portions each with a capacitive coupling element (2) made from an electrically insulating material for producing and maintaining a discharge in the discharge space, characterized in that the lamp is provided with means for preventing the occurrence of (hair) cracks in a wall of the discharge vessel as a result of piezoelectric properties of said electrically insulating material.
